I have received following error when a wnat to "add server":


(pgadmin3:27830): Gtk-CRITICAL **: file gtkliststore.c: line 570: 
assertion `GTK_LIST_STORE (tree_model)->stamp == iter->stamp' failed

and backtrace is following:

....

If I compare it with Dhanaraj problem there are some similar things. In 
both cases some combobox widget is present and some signal occurs. I 
guess that there should be some race condition or some unforgotten 
combobox which receives signals, but it has pointer to non existing memory.
